NgoFebhuwari 2023, i-European Union Scientific Committee for Consumer Safety (SCCS) yakhipha umbono wokugcina mayelana nokuphepha kwabathengi.α-arbutinfuthiβ-arbutinkwezimonyo, kanye nomphumela wokuba mhlophe kwesithako senkanyezi i-arbutin kuphinde kwabangela ukukhathazeka embonini.
Yini i-arbutin?
I-Arbutin (Arbutin), eyaziwa nangokuthi i-arbutin, igama lamakhemikhali i-4-hydroxyphenyl-D-glucopyranoside, isisindo samangqamuzana esihlobene ngu-272.25, iyi-glycoside yemvelo evela ezitshalweni eziluhlaza, izitshalo eziningi ezomisa iqhwa, njengokolweni, i-pear, i-rhododendraceae ithela izithelo ezinothile. kuzixazululi, amakristalu amhlophe aciculate noma impushana, Ancibilika emanzini ashisayo, i-methanol, i-ethanol ne-propylene glycol, i-propylene glycol, engancibiliki ku-ether, i-chloroform, i-petroleum ether nezinye izincibilikisi.
I-Arbutin ingahlukaniswa ngohlobo lwe-α kanye nohlobo lwe-β ngokuya ngesakhiwo esihlukile. I-α-arbutin ngokwekhemikhali ibizwa nge-4-hydroxyphenyl-α-D-glucopyranoside, futhi i-β-arbutin ibizwa ngekhemikhali i-4-hydroxyphenyl-β-D-glucopyranoside. I-Alpha-arbutin iyisomeri ehlukile ye-β-arbutin, futhi isibopho sayo se-glucoside siphambene nendawo naleyo ye-β-arbutin (bona umfanekiso).
